MACRYNAL SM 6810w/42WA is used in combination with water-emulsifiable polyisocyanates for high quality 2-pack-topcoats with excellent applicability and appearance.

MACRYNAL VSM 2570/70BAC is a high solids content at application viscosity- Good drying speed. Good adhesion to metals. Very Good mechanical properties, Good gloss and Good outdoor durability. Macrynal VSM 2570 is a hydroxy functional acrylic resin cross-linkable with aliphatic polyisocyanates to formulate air drying and forced drying 2-pack high solids coating systems. In pigmented topcoats (pigment/binder = 1 : 1) a solids content of 65 % at application viscosity of 55 s (efflux time DIN EN ISO 2431, 4 mm, 23 °C) can be achieved. To ensure that optimal properties are obtained it is necessary to have complete crosslinking. For stoichiometric (equivalent) crosslinking (NCO : OH = 1 : 1) approx. 100 parts per weight Macrynal VSM 2570 (f.o.d.) require approx. 21 parts per weight Desmodur N 3390 (Covestro). in combination with amines like diethyl amino ethanol (approx. 0.2 %, based on solid resin). Potlife is thereby reduced, however. Dilution Suitable diluents are butyl acetate, methyl isobutyl ketone, 2-methoxypropyl acetate or aromatic solvents like solvent naphtha 150/180. Anhydrous solvents as well as solvents free of hydroxy functional groups should be used in the presence of isocyanates. Pigments Inert pigments and extenders are suited for pigmentation. Pigments with basic surface treatment can act as additional catalyst and shorten the potlife even more.

Additives To improve levelling ADDITOL VXL 4930 is recommended. ADDITOL VXL 6212 has proved to be an effective wetting agent.

MODAFLOW 9200 is a new low‐viscosity flow modifier developed for high performance in solvent‐based automotive and industrial coatings, especially in clear top coat applications where it offers high gloss, low orange peel, and excellent DOI (Distinctivness of Image) in the coating film. Using of Modaflow 9200 can significantly improve the quality of the coatings as follows: improves flow and leveling, reduces pinholes, fisheyes, craters and orange peel, improves substrate wetting, improves or maintain high gloss, improves or maintain substrate and intercoat adhesion, facilitates pigment dispersion, quantity to be added: 0.1 ‐ 2.0 % on solid resin.

MODAFLOW AQ 3025 is an acrylic flow additive for aqueous coatings. It has been developed for use in water-reducible, latex, and dispersion systems and is compatible with a broad range of chemistries. Modaflow AQ 3025 is amine neutralized in water and contains no organic solvents or silicone. The low viscosity of Modaflow allows for easy incorporation into the coating formulation versus Modaflow AQ 3000.
